If you can, set up against a wall or other vertical support where you can stack your hips and shoulders. Put a band above your knees. * Lying on your side, stack your hips and shoulders, keeping your spine long and supporting your head so it's comfortable * Bend your knees to 90 degrees, placing your feet in line with your shoulders and hips * Drive out against the resistance of the band through your hip's range of motion * Make sure your hips don't roll forward or spine collapses/hip hitches toward the shoulder to do this move -- use the support behind you as a physical cue!
